Edgar Casey - Is He a Conscious Fraud?

Most people who have looked into casey have concluded that he was sincere and not a conscious fraud. Edgar casey is the best documented psychic of all time, meaning we have more documentation about his activities than any one else. And so n i don't believe anyone has ever questioned his sincerity. For example, super sceptic james randy did. But then brandy had an extreme bias and would accuse basically any one of being a hoaxer - even when he didn't have evidence.
